0001 # Merge Tiles in Barrel HCal
0002
0003 An EICrecon plugin and ruby script to merge adjacent tiles in the BHCal and process
0004 the merged tiles up to the `CalorimeterClusterShape` algorithm. These illustrate
0005 two points:
0006
0007 - The plugin illustrates how to create a custom plugin which wires together
0008 a new sequence of algorithms that *aren't* run in the default plugins.
0009 - And the script illustrates how to call this plugin and update the tile-
0010 merging parameters and adjacency matrix for the BHCal self-consistently.
0011
0012 Reads in either DD4hep output or EICrecon output which contain the `HcalBarrelRecHits`
0013 collection. User options are either set in `RunEICReconWithTileMerging.rb` or from
0014 the commandline (see below).
0015
0016 ## Dependencies
0017
0018 Requires all of the usual dependencies for EICrecon (PODIO, EDM4hep, EDM4eic,
0019 DD4hep, etc.)
0020
0021 ## Usage
0022
0023 First, the plugin will need to be compiled:
0024
0025 ```
0026 # set installation path if you haven't already
0027 mkdir ~/EICrecon_MY
0028 export EICrecon_MY=~/EICrecon_MY
0029
0030 # now build plugin
0031 cmake -S ClusterMergedHits -B ClusterMergedHits/build
0032 cmake --build ClusterMergedHits/build --target install -- -j8
0033 ```
0034
0035 Things like input/output files are set in `RunEICReconWithTileMerging.rb`.
0036 And then we can run EICrecon and merge `N` adjacent tiles together with:
0037
0038
0039 ```
0040 ./RunEICReconWithTileMerging.rb <N>
0041 ```
